Okay, this question has been asked enough times that I think we can have a single thread/sticky with the correct info for everyone concerned 
Here are your options if you want a Vista 64-bit DVD:
1. Buy Vista Ultimate. Its the only edition that comes with 32 AND 64-bit disks by default.
NOT recommended because of the higher cost and the fact that for normal use, the Home Premium edition is more than sufficient.
2. For any other version of Vista, you need to buy a legitimate copy (32-bit of course). The, contact MS support (phone/email/online) and ask them to ship you a corresponding 64-bit DVD. You WILL be charges DVD + shipping + handling charges for this. Should be around 1k?
See: Windows Vista Alternate Media
3. RECOMMENDED Method:
One thing you NEED to know. Serial key etc for both 32 and 64-bit WILL be the same. All you need is installation media.
Hence, simplest solution:
a. Go get yourself a normal legit 32-bit RETAIL copy.
b. Get a copy of the 64-bit installation disc from a friend OR just get your hands on a 30-day trial version of Vista OR simply download a copy of the Vista 64-bit DVD from one of the many sources out there.
c. Install using this copy BUT with your legitimate product key.
And Voila! Legit 64-bit Vista.
MISC:
1. MS will NOT supply 64-bit discs for OEM copies of Vista (for example, the one you get with laptops preinstalled). For OEM copies, please contact your manufacturer and check IF they will provide you with one (pretty rare I think). You will probably STILL be able to use step 3 above to install the same. So long as the serial is yours, there shouldnt be any issue of 'authenticity' as such.
2. Since there is only one serial, you CANNOT install 32-bit AND 64-bit versions on 2 different machines at the same time.
